Is it possible to make two different backup over two external HD with time machine?

The problem:
Into my iMAC I have 1) work (text and design and photo) and 2) photo (my hobby)
Directory of work is quite light, and Time Machine is very appropriate
The directory photo is very big, many Gb, and TM cancel old backup of work and photo.
I want, if possible:
To make the backup  of Works on the first external HD, excluded the files of directory Photo
To make the bacup of photo on the second external HD, excluded the files of directory Works
Thanks,

Using TimeMachine you can have more than one backup drive but only set up a single set of exclusions. To do what you want to do will require another backup program. For example you might use TimeMachine to back up your documents and then another program, such as ChronoSync, to back up just your photos.

  • I backup to an external hdd with Time Machine, when it ran out of space it did not delete old backups, now my internal hdd says its full when before it had heaps of space. I have searched for extra files but cant find any. Can anyone help, please.

    First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.
    To locate large files, you can use Spotlight as described here. That method may not find large folders that contain a lot of small files.
    You can also use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
    Proceed further only if the problem hasn't been solved.
    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
    Back up all data now.
    Install ODS in the Applications folder as usual.
    Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
    When you're done with ODS, quit it and also quit Terminal.

  • HT201250 Backup using lacie external drive with time machine

    Hi, I recently backed up my macbook with a lacie external hard drive using time machine.  However, when i try to open my photos, which says there is 11.67GB there, nothing happens.  It only opens an empty file.  After my backup i deleted the photos from my laptop, after all i was trying to clear disc space on my macbook.  Can i resolve this or can i open the file in a different way?  Help

    One should always confirm copied stuff is where they think it is before deleting the original stuff. See Pondini's TM FAQs, for starters.

    I would like to backup my external HD with Time Machine in the HD of TC. Is it possible?
    Sorry, but not possible.
    Time Machine can only back up the internal drive(s) in a Mac....or a drive that is connected directly to a Mac via USB or FireWire.....provided that the drive is formatted in Mac OS Extended (Journaled).
    I am not recommending this, but you might be able to move the drive from the USB port to the Mac, and have Time Machine back it up that way.....then move it back to the USB port on the Time Capsule......but this will involve doing some risky things.....and manually changing settings around everytime you make the swap. Something will surely go wrong....but up to you if you want to try it.
    Carbon Copy Cloner will back up the drive connected to the USB port on the Time Capsule to the Time Capsule disk, but these will not be Time Machine backups.  SuperDuper claims to also be able to do this.....but I have not tested it.

  • Can I use a 2tb external drive with Time Machine to backup my Mac Mini (256gbSSD + 2tbHDD)?

    Can I use a 2tb external drive with Time Machine to backup what I have on my Mac Mini?
    My Mac Mini has one 256 SSD and one 2tb HDD. I want to use Time Machine to do a backup of everything.
    Would an external 2tb My Passport Drive by Western Digital work for the backup?
    It seems like it would not work because the total storage on the Mac Mini is 2304 gigabytes (SSD + HDD).
    And the external Western Digital drive is only 2048 in gigabytes versus 2304 gigabytes the Mac Mini has.

    No. A Time Machine backup drive should have at least twice the capacity of the drive it backs up. You would need at least a 4 TB backup drive for Time Machine.
    Might I suggest as an alternative that you not use Time Machine but a third-party backup utility that simply overwrites older files with new ones such that the backup drive can be the same capacity as the drive backed up.

  • Can I backup two Apple computers to one hard drive with time machine?

    I have a 2007-vintage MacBook Pro running iOSX 10.6.8 and an iMac  running 10.5.8 -- Can I use a single external hard drive along with Time Machine to backup both of these computers without any problems?  The hard drive has already been backing up the iMac for a few weeks now and the SeaGate drive had to be reformatted to do that. How will I be able to separate the information saved on the hard drive to know which computer is which? (i.e., how "smart" is Time Machine's file structuring when it makes a backup?)

    Do you mean you want to connect a USB drive to the TC?  If so, it will recognize a disk formatted in FAT32, but not ExFAT or NTFS.
    If you mean you want a Windoze-like partition on the TC's internal HD, that's a bit trickier, since it can't be partitioned.  But you could create a disk image on it via Disk Utility, formatted MS-DOS (FAT) aka FAT32, or ExFAT  (I'm not entirely sure if ExFAT would work in a disk image there, but it might.)

  • Can I backup another external HD with Time Machine/Capsule?

    I have two external 250GB hard drives hooked up to my mac via USB. One for Time Machine and one for files. Does anyone know if it’s possible to backup my external HD for files to the external HD for Time Machine?

    using the usb connected to the TC the readme says its doable. Just try it , what can it hurt unless you have valuable files on it.

  • Can't use two external drives with time machine

    I have 2 external drives.  I tell time machine that I have 2 and it asks if I want to use both.  I say yes and it says it will alternate between them.  However, after backing up to both, it then will invariably say that one doesn't have enough room for backup...as if it is trying a new backup......  rather than just adding changed files.  Why is it doing this and how do I remedy?

    It then will invariably say that one doesn't have enough room for backup
    Unfortunately, these kinds of things are common with Mavericks. All that you can do is erase the drive and start over again with a new backup. Or, if you do not want to erase the drive, set it aside in a safe place and add a new drive....and Mavericks will make a full backup to that one to start things off.

  • Can you utilize Time Capsule to backup Windows 7 files simultaneously with Time Machine backing up your MacBook?

    Can you use the Time Capsule 2TB to backup files from a PC (using the standard backup program in Windows 7) while also using the TC 2TB to run Time Machine to backup a MacBook?

    Yes, it will work fine.. at least until the disk starts to fill up, then the expanding size of the sparsebundle can cause issues with the files from windows.. Pondini has made note of the issues..
    http://pondini.org/TM/TCQ3.html
    but I have to admit to doing precisely what you are talking about without problems.. as long as you maintain space.. plenty of space. Time Machine is eventually designed to use up all space on the TC.
    You cannot partition the TC drive without opening the TC and breaking warranty.. but you can create a disk image and put your windows backups inside it.. that might help to prevent issues.

  • Is it possible to set up a backup between two external drives

    Is it possible to set up a backup between two external drives?
    i use time machine to back up my imac onto an external 2T.
    i also have two external 3T drives.  i am looking for redundancy of data, tried software RAID and it failed.  i also see some limitations with RAID that a backup would avoid.
    thanks for sharing your expertise.
    be well,
    tony

    so thanks to all of you, particularly rkaufmann87 i have decided to stop the plan of setting up a software RAID set.  instead i have downloaded ccc and am in the process of setting up the secone 3t external drive as a clone.  i will use time machine to back up the internal hard drive only and if possible see if i can clone that as well onto one of the 3t's.
    this gives me the peace of mind i sounght and avoids the problem of total corruption that exists with the raid solution i was exploring.
    thank you all for making this an enjoyable and informative experience.  what a powerful community.

  • Backup with Time Machine on 2 different Hard Drive

    Hello,
    I'd like to know if I can backup *all my data on 2 different external hard drives*. The aim is to a double backup in case of big issue.
    I'd like to process on this way:
    - only one of my backup HD at home and the other is at the office
    - when I plug one of the backup HD, its data is updated according to the previous backup with this HD (not with the other one)
    - if I backup my MBPro just before leaving the office (on the office's HD) and I backup my MBPro just after arriving at home (on the home's HD), my 2 HD should have the state and exactly the same backuped data.
    Is it possible ? Otherwise, is there another way to proceed ?
    Thanks for all,
    Malphas

    *Using Time Machine with Multiple Destination Hard Disks*
    Yes, this is possible, as long as you understand how it works. First, Time Machine is only designed to work automatically with one backup disk. If you are going to employ multiple Time Machine disk with a single Mac, then you are going to have to manually select the new drive each time it is attached using the Time Machine Preferences “Change Disk…” button.
    Secondly, Time Machine *+does not+* ordinarily perform file-by-file comparisons to determine what has changed and thus determine what needs to be backed up. Rather, Time Machine relies on FSEvents notifications. This is a log that the system uses to keep track of changes to directories. Rather than scan tens of thousands of files for changes each time, Time Machine simply looks at this log and narrows its’ scan to only the directories that have experienced changes since the last backup.
    Every event that FSEvents records has its’ own ID which includes a time stamp. At the end of every backup, Time Machine stores the last event ID that it processes. When the next backup is initiated, Time Machine looks at this stored ID and determines that it only needs to backup events that have occurred after the time stamp on this last event ID.
    Naturally, for hourly backups, Time Machine does not have to go back very far to find the last known event ID. However, if a Time Machine disk is only being attach for backups every few days, a week, or more, and Time Machine has to go back too far to find the last event ID, then it will give up and simply go into “deep traversal” and do the file-by-file scan on its’ own. There are simply too many events logged by the system for Time Machine to bother looking for the last known event ID. Consequently, expect lengthy “Preparing Backup…” sessions anytime you attach a backup disk infrequently.
    Nevertheless, using Time Machine with multiple destination disk will work. If the two drives are routinely backed up then they will always remain in relative sync.
    Finally, remember to reselect your normal Time Machine disk in the Preferences when the backup to the secondary disk is complete.
    Hope this helped clarifies things a bit for you.
    Cheers!

  • Is there a way to have two different iTunes for two different iPhones on one Windows User account?

    Using Windows 7, iphone 4.
    I've read as many threads on these forums and as many kb's as I could find, but I sttill can't figure it out. I have 2 iPhones. Let's call them, "wife" and "hubby". I want to have two separate iTunes, one for each of the phones. Hubby is the Windoows User. I don't want to set up a different Windows User for wife.
    Hubby was the original iPhone. When I plug it in, iTunes recognized it has Hubby's iPhone. Then I unplug Hubby and close iTunes. I plug in Wife but iTunes stll comes up with Hubby under Devices and syncs Hubby's iTunes to Wife's iphone.
    I've tried using the shift key when I open iTunes to set up two separate .itl files to no avail.
    Is there a way to have two different iTunes for two different iPhones on one Windows User account?
    Thanks!

    What happens if you rename the iPhone "Wife" when it shows up as "Hubby", then choose a different set of apps/playlists to sync with? iTunes is supposed to be able to manage multiple devices, each with their own selection of content. Perhaps you "restored" "Wife" with a backup from "Hubby" when you first set things up which is now causing confusion.
    To create a new library press and hold down the shift key as you click the icon to start iTunes and keep holding shift until asked to choose or create a library. You need to use the same technique to switch back.

  • How can I split a backup on two hard drives with Time Machine ?

    Back-up of my Imac with time machine is 1,3 TB. I have two 1 TB external hard drives but even if I had both as available in Time machine, it seems it doesn't allow to split the backup between the two hard drives. Any way to resolve this without buying another hard drive with more space?
    Thanks in advance

    You cannot directly split a backup. Your only option would be to open the TimeMachine preferences from System Prefs. and add things to the exclusion list for one of the backups. Then, when you go to do the other backup you would reverse the process and add everything else to the exclusion list and remove the things you had on there in the first place.
    Seems fairly intensive though when you could just go and buy a 2 or 3TB external drive and do it all in one...Black Friday is coming up

    Doug is correct. Both analog outputs have a shared clock. If you want to write to both outputs simultaneously, you will need to include both of them in the same operation (group).
    You can write a 2-D array to the AO Write VI in which you can include data for both channels. In the 2-D array, column 1 will be for the first channel in the channel list and column 2 will be for the second channel.
    I hope this helps.
